In attempting to assess the legacy of Paul Feyerabend's philosophical
work, matters are complicated by the fact that there was a change in h
is basic orientation towards the philosophy of science around the end
of the 1960s. Here I shall indicate one aspect of Feyerabend's divided
legacy. My main aims are to sketch the principal themes in his (fairl
y extensive but little-known) 1990s output, to situate that later outp
ut insofar as it bears on the realism/antirealism debate, and (rather
precipitously, perhaps) to identify what I take to be the single commo
n premise of his entire philosophical work.
